PHP - While Loop To Pick A Certain Type From Db??

Hi guys,

I need to pick the middle five numbers from a range of numbers

example

$lowest number = 0;  // this will allways be 0

$highest_number = 10; // this can very from 1 to 10000

$selected_number = 5; // this can also very but it will allways be between 0 and highest number

the middles numbers from the above 3 varuables should be
3 4 5 6 7 --- the $selected_number number allways needs to be the middle number


// some of the issue we need to watch out for is, if hughest number is 4 then it should just go
1 2 3 4




Thank you guys

I am creating a program to simulate the Powerball Lottery game, I have everything working but i forgot to add the Quick Pick Option, having alittle bit of an issue with my "if" statement I believe. My confusion is whether it should be a nested "if", or should it be it's own entity?
Here's what i have so far:

Code: [Select]
<?php
 
        $intGrandPize = 10000000;
         $intRegCount = 5;
         $intMaxReg = 59;

 //$quick = rand(1, 59);
 //$quickPB = rand(1, 49);
 if (isset($_POST['Quick Pick'])){
 
        if (count($_POST)>0) {
             $aryPick = array();
             $intPower = 0;
             for($t=1;$t<=$intRegCount;$t++) {
                 if (isset($_POST['num'.$t])) {
                     $intPick = (int)$_POST['num'.$t];
                     if ($intPick > 0 && $intPick <= $intMaxReg && !in_array($intPick,$aryPick)) {
                         $aryPick[] = $intPick;
                     }
                 }
             }
             if (isset($_POST['Power']) && (int)$_POST['Power'] > 0 && $_POST['Power'] <= $intMaxPB) {
                 $intPower = (int)$_POST['Power'];
             }
             if (count($aryPick) < 5 || $intPower == 0) {
                 echo "<font color='red'>'*Five unique numbers and a PowerBall selection are Required*'</font>";;
             }
             else {

I Have the following issue and I spend my whole day looking for it.

I have a database with a simple admin where I add/delete values.

The database structure is the following:

id, zip, email
The database is called zipdatabase

Here is the mailing part:

Code: [Select]
//headers
$headers = "From: <$Email>";
$headers .= "\r\nBcc: <$Bcc>\r\n\r\n";

// send email
$success = mail($EmailTo, $Subject, $Body, $headers);The variable $Bcc must come from the database. I am really ignorant so I only got to a point on how to echo the results I need (and this works):
Code: [Select]
$query  = "SELECT email FROM zipdatabase WHERE zip = '$ZIP'";
$result = mysql_query($query);
while($row = mysql_fetch_array($result))
{
   echo "{$r['email']}, ";
}
?>
For a zip I get more than one result so when I tried using this

Code: [Select]
$query  = "SELECT email FROM zipdatabase WHERE zip = '$ZIP'";
$result = mysql_query($query);
while($row = mysql_fetch_array($result))
{
   $Bcc = "{$r['email']}, ";
}
echo "Bcc"
?>
It only gives me one result.

What I noticed is I have 2 issues:
- I can't extract the BCC from the database
- I don't know how to add more email addresses to the bcc field, I only managed to add more addresses to the $Emailto like:
Code: [Select]
$EmailTo = "address1@domain.com, address2@domain.com";
$Bcc = "address3@domain.com";
All these variables are defined by a webform and it works flawlessly except the database problem:

Code: [Select]
$Name = Trim(stripslashes($_POST['Name']));
$Phone = Trim(stripslashes($_POST['Phone']));
$ZIP = Trim(stripslashes($_POST['ZIP']));
$Email = Trim(stripslashes($_POST['Email']));
$Message = Trim(stripslashes($_POST['Message']));

// validation
$validationOK=true;
if (!$validationOK) {
  print "<meta http-equiv=\"refresh\" content=\"0;URL=contacterror.htm\">";
  exit;
}

// prepare email body text
$Body = "";
$Body .= "Name: ";
$Body .= $Name;
$Body .= "\n";
$Body .= "Phone: ";
$Body .= $Phone;
$Body .= "\n";
$Body .= "ZIP: ";
$Body .= $ZIP;
$Body .= "\n";
$Body .= "Email: ";
$Body .= $Email;
$Body .= "\n";
$Body .= "Message: ";
$Body .= $Message;
$Body .= "\n";

Sorry for my ignorance and hope someone here can help.
The webform works perfectly except the bcc from the database part.

Code: [Select]
function choose_numbers($number,$max) {
global $ibforums,$std;
srand( (double)microtime() * 1000000 );
$array = array();
$i = 0;
while($i!=$number)
{
$array[] = mt_rand(1,$max);
$i++;
}
$c = count($array);
while($c != $number)
{
$array[] = mt_rand(1,$max);
$c = count($array);
if($c == $number)
{
$array = array_unique($array);
$c = count($array);
}
}
return $array;
}
$newnumbers = $this->choose_numbers(3,36);
echo "{$newnumbers['0']}|{$newnumbers['1']}|{$newnumbers['2']}";

This echo's out my lottery balls 0|32|22 or technically RANDNuMbER|RANDNUMBER|RANDNUMBER

up to 36 is the highest number.

Now my issue is, I don't want 2 numbers of the same Value, EVER. Sometimes it does 2|3|2 which is BAD (for my lottery system) is there anyway I can make it so it never will echo out 2 (OR 3) of the same number?

Hi,

I need to write some code for this but unsure where to start.

Basically i have a database of say 10 rows. I need to be able to input a number and some sort of fair algorithm will choose one of the rows.

The number will be from 6 to 10 numbers long, and will need to pick the same result each time based on that number.

Its for a lotto game

I developed this game and I couldn't figure how to make random only on available shot glasses but it would still random with unavailable shot glasses.  I simple give up.  I plan to share this php once I nailed it down but apparently, not successful.  Now, I'm share with you anyway.  If you can solve the problem and please let us know!

Hey.   So the issue I'm having is consecutive loops on semi-large arrays, over and over. Consider this array:

$firstArray = array(
'row1' => array(
'dates' => array(
'2014-01-01' => array('key1' => 'value1', 'key2' => 'value2', 'key3' => 'value3', 'key4' => 'value4', 'key5' => 'value5', 'key6' => 'value6', 'key7' => 'value7', 'key8' => 'value8', 'key9' => 'value9', 'key10' => 'value10'),
'2014-01-02' => array('key1' => 'value1', 'key2' => 'value2', 'key3' => 'value3', 'key4' => 'value4', 'key5' => 'value5', 'key6' => 'value6', 'key7' => 'value7', 'key8' => 'value8', 'key9' => 'value9', 'key10' => 'value10'),

Originally the data comes from ~2-3 database tables, of course. But to ilustrate the point, this is how the main array looks like. This array usually contains anywhere between 10-50 rows, each row containing at least 10 dates, with 10 key/values each.   And after setting up all the data, it needs to be processed. Currently this is how a friend of mine did it..

$placeDataHere = array();
foreach($firstArray as $key => $dates) {
foreach($dates as $date => $values) {
foreach($values as $key => $value) {
$placeDataHere['DV_' . $date]['SM_' . $key] = 'KS_' . $value;
//Followed by another ~50-70 lines of processing the 3 loop's data..
...
...
....
....
....
....
....
....
}
}
}

Obviously this isn't good practise, but we can't seem to figure out a better way of doing it, since both the data and the loops are horribly nested.   This loop and setup of $firstArray is run anywhere between 10-20 times/request, due to amount of users we wish to process. So, the result is that this code can take up to over 2-3 minutes to complete, which isn't really optimal performance.   In short my question is, are there any better methods of handling this with the data setup we currently have?

Below is my output on the browser:

    Student: Kevin Smith (u0867587)
    Course: INFO101 - Bsc Information Communication Technology Course Mark 70 Grade
    Year: 3
   
   
    Module: CHI2550 - Modern Database Applications Module Mark: 41 Mark Percentage: 68 Grade: B
   
    Session: AAB Session Mark: 72 Session Weight Contribution 20%
   
    Session: AAE Session Mark: 67 Session Weight Contribution 40%


    Module: CHI2513 - Systems Strategy Module Mark: 31 Mark Percentage: 62 Grade: B
   
    Session: AAD Session Mark: 61 Session Weight Contribution 50%

Now where it says course mark above it says 70. This is incorrect as it should be 65 (The average between the module marks percentage should be 65 in the example above) but for some stange reason I can get the answer 65. I have a variable called $courseMark and that does the calculation. Now if the $courseMark is echo outside the where loop, then it will equal 65 but if it is put in while loop where I want the variable to be displayed, then it adds up to 70. Why does it do this.
   
    Below is the code:

Code: [Select]
    $sessionMark = 0;
    $sessionWeight = 0;
    $courseMark = 0;
   
    $output = "";
   
    $studentId = false;
    $courseId  = false;
    $moduleId  = false;
   
    while ($row = mysql_fetch_array($result))
    {
   
   
    $sessionMark += round($row['Mark'] / 100 * $row['SessionWeight']);
    $sessionWeight  += ($row['SessionWeight']);
        $courseMark = ($sessionMark /  $sessionWeight * 100);
   
          if($studentId != $row['StudentUsername'])
        {
   
            //Student has changed
            $studentId = $row['StudentUsername'];
   
            $output .= "<p><strong>Student:</strong> {$row['StudentForename']} {$row['StudentSurname']} ({$row['StudentUsername']})\n";
   
        }
             
        if($courseId != $row['CourseId'])
        {
   
            //Course has changed
            $courseId = $row['CourseId'];
   
            $output .= "<br><strong>Course:</strong> {$row['CourseId']} - {$row['CourseName']} <strong>Course Mark</strong>" round($courseMark) "<strong>Grade</strong>  <br><strong>Year:</strong> {$row['Year']}</p>\n";
   
        }
   
        if($moduleId != $row['ModuleId'])
        {
   
            //Module has changed
            if(isset($sessionsAry)) //Don't run function for first record
            {
   
                //Get output for last module and sessions
                $output .= outputModule($moduleId, $moduleName, $sessionsAry);
            }
   
            //Reset sessions data array and Set values for new module
   
            $sessionsAry = array();
            $moduleId    = $row['ModuleId'];
            $moduleName  = $row['ModuleName'];
        }
             
        //Add session data to array for current module
             
        $sessionsAry[] = array('SessionId'=>$row['SessionId'], 'Mark'=>$row['Mark'], 'SessionWeight'=>$row['SessionWeight']);
             
    }    //Get output for last module
   
    $output .= outputModule($moduleId, $moduleName, $sessionsAry);
   
    //Display the output
    echo $output;
I think the problem is that it is outputting the answer of the calculation only for the first session mark. How in the while loop can I do it so it doesn't display it for the first mark only but for all the session marks so that it ends up showing the correct answer 65 and not 72?

Probably a stupid question . . .   The MIME type in my php.ini file is set to text/html:

default_mimetype = "text/html"

But, because I use XHTML 1.0 Strict, the MIME type of my web pages is set to text/xml:

<meta http-equiv="content-type" content="text/xml; charset=utf-8" />

I should therefore change the php.ini MIME type to text/xml, right?  

Hey guys,

Got another question im hoping someone can help me with.

I have a foreach loop (for use in a mysql query):

   foreach ($interests as $interest) {
       $query .= "($id, $interest), ";
   }

problem is i do not want the comma(,) in the last loop.

Is there some kinda of function i can use so it does not insert it on last loop?

Or should i just use a for loop with a nested if loop? something like ;

   for($i=0; $i < count($interests); $i++){
      $query .=
      "($id, '$interests[$i]')";
      if($i + 1 < count($interests)) {
         $query .= ", ";
      }
      }


Cheers guys

I am working to echo the results in a while or for loop... Both of my sample codes work, but the results are wrong!

The while loop ONLY echos a result IF the first record in the postings table matches the id passed (does not display a result unless the first record has a match)

The if loop displays ALL listings with the same name (counts them all) so there are no unique listings!


<?php

$posts_by_city_sql = "SELECT * FROM postings WHERE id='$_GET[id]'";
$posts_by_city_results = (mysqli_query($cxn, $posts_by_city_sql)) or die("Was not able to grab the Postings!");

/* While Loop  */
while($posts_by_city_row = mysqli_fetch_array($posts_by_city_results)) {
echo "<li><a href='posting_details.php?id=$posts_by_city_row[id]'>$posts_by_city_row[title]</a></li>";
}

/* For Loop  */
$posts_by_city_row = mysqli_fetch_array($posts_by_city_results);
 
for ($i=0; $i<sizeof($posts_by_city_row); $i++) {
echo "<li><a href='posting_details.php?id=$posts_by_city_row[id]'>$posts_by_city_row[title]</a></li>";
 }

?>

Results with for loop (there are 7 total unique book names, but it's just counting the first match on id 7 times like below):

Good Evening -  I am in the process of trying to call back a list of categories and sub categories using a WHILE LOOP inside of a WHILE LOOP. It works on a different part of the site within the admin panel but not here. Here it only calls one sub category and moves on to the next parent category instead of finishing the loop and pulling all sub categories out...

// CATEGORIES

$query  = "SELECT * FROM cat";
$result = mysql_query($query);



while($row = mysql_fetch_array($result, MYSQL_ASSOC))
{

$catid = $row['id'];
$catname = $row['name'];

$output .= "<li class=\"level0 nav-2 parent\" onmouseover=\"toggleMenu(this,1)\" onmouseout=\"toggleMenu(this,0)\">
<a href=\"product.php?cat=$catid\">
<span>$catname</span>
</a>\n";


$querynav = "SELECT * FROM subcat WHERE pid = '$catid'";
$resultnav = mysql_query($querynav);

while($array = mysql_fetch_array($resultnav, MYSQL_ASSOC))
{

$subcatid = $row['id'];
$subcatname = $row['name'];

$output .= "<ul class=\"level0\">
<li class=\"level1 nav-2-1 first\">
<a href=\"product.php?cat=$catid&subid=$subcatid\">
<span>$subcatname</span>
</a>
</li>
</ul>
</li>";
}

}
